if you do not explain what you want, and if you do not answer my questions about what you want, nobody ever will be able to help you with that, and a question is not an attack.
if you want to aquire TDM plug-ins, no matter if for using them or for collecting with them, you can download them from here since about 8 years, but you obviously did not do that.
instead you make up storytales about secrets only you know, which says that it would not exist - and five minutes later you request to have information about the beta version.
and then you are not willing to explain what kind of information you mean. beta versions usually do not have a printed manual, the release had one. the manual is only place here you can find information about the software.
if you want to collect beta versions in addition to releases you will probably have to convince others first that this makes any sense, and even then you will find out that the chance is very, very low that somebody will actually have those and is willing to share.
about the usual DAE errors issues with spectralizer and magneto i cannot help, as i am not a protools user. i just remember that some people bought those 30 years ago and then could not use it bc of the part.
the right place to request magneto TDM is the newsboard in the hotline server. since we have it since 30 years, such request will be deleted there, though.
this is the forum thread about freefilter VST.
